AWS Glue Studio validates the JSON config file before custom visual transforms are loaded into AWS Glue Studio. Validation includes:
-
Presence of required fields
-
JSON format validation
-
Incorrect or invalid parameters
-
Presence of both the .py and .json files in the same Amazon S3 path
-
Matching filenames for the .py and .json
If validation succeeds, the transform is listed in the list of available Actions in the visual editor. If a custom icon has been provided, it should be visible beside the Action.
If validation fails, AWS Glue Studio does not load the custom visual transform.
